Node Version Manager (NVM) is a widely used tool among developers that allows them to switch between different versions of Node.js with ease. By default, NVM uses the latest stable version of Node.js, but you can set a default version to use as your system default.
In this article, we will guide you through the steps of setting a default version of Node.js using NVM. We will also provide you with some code examples to help you better understand the process.
Step 1: Install NVM
Before we can set a default version, we need to have NVM installed on our system. If you don't already have it installed, you can follow the steps in this article to install NVM.
Step 2: View Current Node.js Version
Once you have NVM installed, you can view the list of available Node.js versions by running the following command in your terminal:
nvm ls-remote
This will display a list of available Node.js versions that you can install and use.
Step 3: Install Specific Node.js Version
To install a specific Node.js version, you can run the following command:
nvm install <Node Version>
Replace <Node Version> with the version you want to install. For example:
nvm install 14.17.6
This will install Node.js version 14.17.6.
Step 4: Set Default Node.js Version
Now that we have installed a specific Node.js version, we can set it as our default version by running the following command:
nvm alias default <Node Version>
Replace <Node Version> with the version you want to set as default. For example:
nvm alias default 14.17.6
This will set Node.js version 14.17.6 as your system default.
Step 5: Verify Default Node.js Version
To verify that your default Node.js version has been set, you can run the following command:
nvm current
This will display the currently active version of Node.js on your system. It should be the same version you set as the default.
Step 6: Switch to a Different Node.js Version
If you want to switch to a different Node.js version, you can run the following command:
nvm use <Node Version>
Replace <Node Version> with the version you want to use. For example:
nvm use 16.6.0
This will switch your active Node.js version to 16.6.0.
Code Examples
Here are some code examples to help you better understand the process of setting a default Node.js version using NVM.
Example 1: Install and Set Default Node.js Version
# Install Node.js version 14.17.6
nvm install 14.17.6
# Set Node.js version 14.17.6 as default
nvm alias default 14.17.6
Example 2: Verify Default Node.js Version
# Display currently active Node.js version
nvm current
Output:
v14.17.6
Example 3: Switch to a Different Node.js Version
# Switch to Node.js version 16.6.0
nvm use 16.6.0
Conclusion
In conclusion, NVM is a great tool for managing different versions of Node.js on your system. Setting a default version is simple and can be done with just a few commands in your terminal. We hope this article has provided you with a better understanding of how to set a default Node.js version using NVM and provided you with some useful code examples.
- NVM:
Node Version Manager (NVM) is a command-line tool that helps manage multiple versions of Node.js on a single system. NVM makes it easy to switch between different versions of Node.js that are installed on your system. It is particularly useful for developers who need to work on different projects that require different versions of Node.js.
One of the key advantages of using NVM is that it allows you to install and use different versions of Node.js without interfering with each other. You can install as many versions as you need, and switch between them easily with just one command.
In addition to setting a default version, NVM provides a number of other useful features, such as listing available versions, installing specific versions, and managing aliases. With NVM, you can easily experiment with different versions of Node.js and choose the one that works best for your needs.
- Set Default Version:
Setting a default version with NVM is a straightforward process. With just a few commands, you can set a default version of Node.js that will be used by your system.
First, install NVM on your system using the appropriate installation instructions for your operating system. Once installed, use the "nvm ls-remote" command to view the list of available Node.js versions.
Next, install the version of Node.js that you want to set as the default. Once installed, run the "nvm alias default" command to set the default version. For example, "nvm alias default 14.17.6" will set Node.js version 14.17.6 as your default version.
Finally, verify that your default version has been set by running the "nvm current" command. This will display the currently active version of Node.js on your system.
Setting a default version with NVM is particularly useful if you have a project that requires a specific version of Node.js. By setting a default version, you can ensure that that version is always used by your system by default, making it easier to manage your projects.
- Code Examples:
Here are some additional code examples that demonstrate how to use NVM to manage multiple versions of Node.js:
Example 1: List Available Versions
# List all available versions of Node.js
nvm ls-remote
Example 2: Install Specific Version
# Install Node.js version 16.6.0
nvm install 16.6.0
Example 3: Use Specific Version
# Use Node.js version 16.6.0
nvm use 16.6.0
Example 4: List Installed Versions
# List all installed versions of Node.js
nvm ls
Example 5: Uninstall Specific Version
# Uninstall Node.js version 14.15.4
nvm uninstall 14.15.4
NVM provides a number of other useful commands for managing multiple versions of Node.js. By learning how to use these commands, you can easily switch between different versions of Node.js and choose the one that works best for your needs.
